VICI Valco Driver with Rotor Pin Lot of 8 Units

VICI Valco Driver with Rotor Pin – Precision Valve Alignment Interface, Stainless Steel / High-Torque Coupling, Zero-Backlash Indexing (MPN: Valco Valve Driver Series)

The VICI Valco Driver with Rotor Pin is an instrument-grade mechanical coupling component engineered to establish the direct physical interface between a manual or automated actuator drive shaft and the inner polymer rotor of a Valco gas or liquid chromatography valve. This precision-machined module consists of a durable cylindrical driver body equipped with a hardened, offset rotor pin. The pin is designed to slot perfectly into the back-face alignment notch of the valve's internal rotor block. By converting the rotational torque of the actuator directly into absolute, dual-position switching or multi-position indexing movements, this sub-assembly guarantees pristine flow-path registration. The anti-backlash structural profile eliminates rotational lag and axial wobble, ensuring that internal micro-capillary channels align flawlessly to maintain low residual volumes and sharp analytical peak resolutions.

Technical Performance and Design

• Hardened Precision Rotor Pin: Features an integrated, heavy-duty indexing pin built to exact tolerances. The pin fits securely into matching valve rotor matrices without play, preventing slipping or uneven wear on the rotor interface during high-speed switching loops.

• Zero-Backlash Torque Transfer: The mechanical interface is designed to transmit rotational torque instantly. This configuration completely eliminates positioning delay, ensuring that valves snap precisely into place (such as moving from a "Load" loop to an "Inject" column path) without stopping mid-port.

• Concentric Drive Alignment: Machined from premium, passivated alloys to guarantee perfect axial concentricity. This prevents spindle wobble or uneven side-loading inside the valve body, protecting delicate internal polymer sealing faces from scoring and premature degradation.

• High-Temperature Instrument Resilience: Engineered to perform reliably across a wide operating envelope. The assembly easily handles the continuous high temperatures of gas chromatography ovens without physical distortion or thermal expansion binding.
